210568 divided by 54 
The aim is to understand the frequency of 54 in 210568.

Advancing to step 1:
When dividing 2 by 54, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 54

Advancing to step 2:
The number 54 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 54

On to step 3:
54 goes into 210 3 times with a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 162 from 210 to get 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 54

On to step 4:
If we divide 485 by 54, we get 8 and a remainder of 53.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtracting 432 from 485 leaves us with 53.
Bring next digit (6) of the dividend behind the 53 and repeat the process: 536 / 54

Advancing to step 5:
536 divided by 54 is 9 with a remainder of 50.
Put 9 as the next digit of the answer. 
Result so far: 389.0
Subtract 486 from 536 to get 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 54

Step 6:
54 can be fit into 508 9 times, resulting in a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 3899.0
Subtract 486 from 508 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
If we divide 220 by 54, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 3899.4
Deduct 216 from 220 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
When dividing 40 by 54, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 3899.4
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
54 goes into 400 7 times with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 3899.407
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
The number 54 fits into 220 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 3899.4074
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
If we divide 40 by 54, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3899.4074
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
54 goes into 400 7 times with a remainder of 22.
The next digit of our result is 7. 
Result so far: 3899.407407
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
If we divide 220 by 54, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 3899.4074074
Subtracting 216 from 220 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
54 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3899.4074074
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 3899.4074074, with a leftover of 4e-08.
